The brightness is controlled with the help of the One Button-Lib. | 7 | The following functions are available to make the LED brighter with "SW_H" or darker with "SW_L": | 8 | Simple click, double-click, long click. | 9 | | 10 | The second function "Display_ON" with an additional key "SW_D" switches on an output for a | 11 | multifunctional display for 30 seconds. | 12 | Testet on a ATtiny85 @ 1 MHz (internal) with bootloader and without Bootloader, works well. | 13 | The Sketch uses 2380 bytes (29%) flash space. | 14 | The Serial communication monitoring is only for debugging on a other devices and it do not work with the tiny85 | 15 | It musst be disabled bevore you upload the Code! | 16 | | 17 +-------------------------------------------------------------------------------------------------------------------------------+ 18 | THE FUNCTIONS: | 19 | ============== | 20 | .attachClick: SW_H / SW_L gradually lighter or darker. | 21 | .attachDoubleClick: SW_H / SW_L very light or dark. | 22 | .attachDuringLongPress: SW_H / SW_L dimming via PWM. | 23 | Display_ON: SW_D for 30 seconds. | 24 | | 25 +-------------------------------------------------------------------------------------------------------------------------------+ 26 | WIRING: | 27 | ======= | 28 | ATtiny85 | 29 | __ __ | 30 | RST -|1 \\/ 8|- VCC | 31 | SW_L -|2 7|- SW_D | 32 | SW_H -|3 6|- DISPLAY | 33 | GND -|4____5|- LED | 34 | | 35 +-------------------------------------------------------------------------------------------------------------------------------+ 36 | SOFTWARE INFO | 37 | ============= | 38 | Version: 1.4_Final | 39 | Writen Date: 16-05.2018 | 40 | Autor: Zislaw Kromski kromski@gmx.ch | 41 | Software Info: Arduino IDE_v_1.8.5 https://www.arduino.cc/en/Main/Software | 42 | OneButton.h_v_1.2.0 http://www.mathertel.de/Arduino/OneButtonLibrary.aspx | 43 | | 44 +-------------------------------------------------------------------------------------------------------------------------------+ 45 */ 46 47#include "OneButton.h" 48 49#define LED 0 // Dimmable High power LED over MOSFET driver "attach to a PWM Pin". 50#define DISPLAY 1 // Output-ON signal for the "Multifunktional Time Display" enabled with SW_D for 30 seconds. 51#define AMOUNT 51 // Stepped (255/51 = 5 steps) increment/decrement brightness. 52#define AMOUNTDIMM 10 // Running (255/10 = +/-25 steps)increment/decrement brightness. 53#define SW_D 2 // Button for Display. 54byte brightness = 0;
